Based on your last few sentences, you're going to love Europe. TONS to see and photograph! Fangs sleep info closely mirrored mine. The only exception being if I had the early AMS with the late departure, I'd often sleep closer to 6 hours when I got in and it worked out great. Either way, I generally had more than enough time to get out and about in the town.

Best piece of advice I can give you for sleep is to keep your phone as far away from you as possible and, with the exception of your alarm, keep it on silent. Turn over any alarm clocks and ensure there is nothing that will show you the time when you wake up in the middle of the night (don't look at your phone either). Do not let screens near you when you lay down, they are a huge time suck which will derail your sleep. If you're on first break, make the bed when you go down to preflight the bunk. That saves you a few minutes for when you get down there for your nap. Most crews will want you to keep the blanket down when your break is over (may have changed since rona) and they'll just put their blanket overtop. By the 3rd break, it creates a nice little pillow top lol. Get audio books for the bus rides, some rides can be quite long...cough...CDG/LHR! If you go to FRA a lot, ask their customs people for an extra sheet for stamps in your passport...they stamp every time you enter/exit. I'd also recommend getting the larger book passport next time you renew, it's the same price. If you decide to throw your passport in the safe, put it on your uniform shoe and put them both in the safe, otherwise you may get to the airport and realize your passport is still in the safe. Found out the hard way on that one.

I'd beg to differ on that. While the hotels are more than adequate, I find the rooms of our domestic hotels to be much nicer than most of the European hotels I stayed in. Among other things, it's super annoying that most of them just have the glass door, or glass that covers half of the shower area, which ensures that water covers half the bathroom. Their showers are often narrow and rounded with high side walls and sometimes a step down a few more inches to the floor from the base of the tub. Couple that with a wet floor (reference above) some can be precarious to get out of. I think we had a (younger) FA die a few years back after slipping and hitting their head while getting out of the shower/tub. Depending on the layover, the room heating/cooling can leave something to be desired.

More like an entirely different air line.
